     You may have heard the term "the American Dream". In 1848, James W. Marshall found gold in

California and people began having golden dreams. That 19th century "American Dream" motivated

the Gold Rush and gave California its nickname of the "Golden State".

    The American Dream drove not only 1800s gold-rush prospectors(采矿者)but also waves of

immigrants throughout that century and the next. People from Europe, and a large number of Chinese,

arrived in the US in the 19th century hoping that in America they would find gold in the streets. But

most, instead, worked as railroad laborers. They created the oldest Chinatown, in San Francisco, and

gave the city a Chinese name "the old gold hill".

     In the 20th century, some critics said that it was no longer possible to become prosperous through

determination and hard work. Unfair education for students from poor families and racial discrimination

almost made the American Dream a nightmare(噩梦).

     Then, in the 1990s, California saw a new wave of dreamers in Silicon Valley. People poured their

energy into the Internet. This new chapter of the American Dream attracted many business people and

young talents from China and India to form start-ups and seek fortune in America. Better pay, a nice

house, and a rising standard of living will always be attractive. However, the new American Dream is

no longer just about money. It encourages Americans to consume wisely to protect the environment,

improve the quality of life, and promote social justice.

    The Governor of California, Arnold Schwarzenegger has become the model of the new American

Dream. After years of hard work, he grew from a poor young man from Austria into a super movie

star and then a governor. Many people hope his story can save the American Dream and give California

a brighter future.
